My personal experience with this issue is that my GGM filed her Dec. of Intent 40+ years after she arrived as a young wife. Most of the information she gave about the ship, date, etc. was incorrect. She could only get naturalized if they could verify with manifest and issue a Certificate of Arrival to the Naturalization Service. Alas, no naturalization because she could not remember the information accurately, due to the number of years.
BTW...came across this document in my search of Jambor... you may already have it... Marriage of Helen Jambor, born in New Jersey, living in Cleveland, Ohio, and married in West Virginia. Could this be Steven Jambor's daughter? Groom is Charles Kloczko.
Unfortunately, no parents' names listed... Top right side of image...
